"There's tough new laws in New South Wales. Labor's always said there needs to be national consistency 'cause you'll always have sneaky characters like Andrew Stoner and his state director, who try to find loopholes to raise money," Mr Foley said.

"The Nationals have set up a Cayman Island-style donations haven down in Victoria. Andrew Stoner wants to be Deputy Premier, he's behaving like Christopher Skase."

Nationals state director Ben Franklin says the claims are not true.

"All of the money will come into the National Party in NSW. It will all be disclosed as it must be," Mr Franklin said.

"We won't accept donations from prohibited donors, as we musn't. All of the money that we receive will obviously be under the cap and so forth. So we'll comply with all legislation as we always do."
